  • Origin2026

    Showa's suspension mastery came from a postwar reinvention. Founded in 1938, it was barred from developing aircraft systems after World War II, so it redeployed its aeronautical engineering into vehicle components — and developed the suspension for the fledgling Honda. The damping and precision-tube know-how that now sits under most Honda bikes and cars (and outboard motors and ATVs) is repurposed aircraft technology — a hidden lineage running from a banned wartime industry to the world's largest suspension maker, today folded into the Hitachi Astemo mega-supplier.

    Motorcycle and much road-vehicle suspension is a Japanese duopoly: Showa and KYB (Kayaba) have for 70+ years supplied the majority of the world's surface-transportation suspension, mirroring the keiretsu pairings (Showa↔Honda, which holds a stake; KYB↔Yamaha), with Öhlins as the premium tier (itself built under license by Soqi in Japan). Showa is the suspension equivalent of Brembo-for-brakes — the recognizable OEM 'good fork.' So the two systems that most define how a motorcycle rides and stops — suspension and brakes — each trace to a handful of Japanese specialists most riders never think about.
